I was doing some research on shields, trying to understand "Parry Power" and I came upon this thread. A part of it reads:
For starters, the vast majority of shields don't register the parry as an attack--it will simply go through the enemy without damaging them. Perfect guarding melee attacks doesn't do damage either. Furthermore, shields that do have damaging parries inflict much less damage than their "power" rating suggests.
Now I'm wondering exactly what shields do register a parry as an attack. Why would one shield be considered capable of dealing damage while another one would not?
I think there may be some hints in the shield descriptions, such as this one:
This Lizal shield has been strengthened by adding a different type of metal to the mix. The edge is lined with spikes, so handle with care.
Maybe the "spiked" varients of shields can do offensive parries. I'm looking for a list of exactly which shields can be used to perform a damaging parry.
